Hi
I have a layout utilizing a hairpin filter. I am using ORCAD 10 and have brought the filter in as a collection of obstacles. now i want to 1) keep the Solder mask off the filter and (2) have a copper "keep out" for the ground flood on the top layer. Maybe a exposed copper plated with hard Au 50 uinches since it will be bare copper.
Any ideas on how to do this. Please email scaron@rfintegration.com.
